Built from M42 cobalt steel, it offers superior heat and wear resistance compared to standard high-speed steel cutters. The 17120 measures 5\/8 inches in diameter with a 3\/4 inches depth of cut, making it well suited for structural fabrication, ironworking, and maintenance applications. The Rotaloc twist-style bayonet shank provides a secure, tool-free connection to compatible magnetic drill presses and annular cutter arbors. The bright, uncoated finish allows for easy visual inspection of the cutting edge before and after use. Licensed electricians, ironworkers, and fabricators regularly rely on annular cutters like this one for cleaner, faster hole production than twist drills.\u003c\/p\u003e\n\u003cp\u003eThe HOUGEN 17120 is intended for use on mild steel, stainless steel, and general steel stock. It is a standard choice in structural steel fabrication shops, on-site ironworking, maintenance and repair operations, and mechanical contracting where precise hole sizing through steel is required. The 5\/8 inches shank diameter fits Rotaloc-compatible magnetic drill press chucks and arbor systems. This cutter is sized for applications where a 5\/8 inches finished hole diameter is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction provides extended tool life in hard and abrasive metals\u003c\/li\u003e\n  \u003cli\u003e5\/8 inches cutting diameter with 3\/4 inches depth of cut for through-hole work in standard structural stock\u003c\/li\u003e\n  \u003cli\u003eRotaloc twist-style bayonet shank allows quick, tool-free chuck connection\u003c\/li\u003e\n  \u003cli\u003e5\/8 inches shank diameter fits Rotaloc-compatible magnetic drill press arbors\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish for straightforward edge inspection and reconditioning\u003c\/li\u003e\n  \u003cli\u003eRated for use in mild steel, stainless steel, and general steel applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Rotaloc twist-style compatible magnetic drill presses and annular cutter arbors accepting a 5\/8 inches bayonet shank connection.

Before mounting, ensure the magnetic drill base is firmly seated and energized against a clean, flat steel surface. Use cutting oil or a suitable lubricant during operation to reduce heat buildup and extend cutter life. Inspect the cutting edge and shank connection for wear or damage before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth of Cut\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Rotaloc Twist-Style\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Bayonet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Mild Steel, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HOUGEN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOUGEN","offers":[{"title":"Default Title","offer_id":52012279791922,"sku":"17120","price":50.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e44948522b636ae8a5f369ffb97aa01.jpg?v=1790005317","url":"https:\/\/voomisupply.com\/products\/hougen-17120-annular-cutter-5-8-in-cobalt-rotaloc-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
